Speaking to Radio 1's Nick Grimshaw, Swift said: "I have two British friends. Ed Sheeran is one of my friends and I met Ellie Goulding and she's the coolest girl. I've been obsessed with her records for a really long time.

"I felt a little fan girl-ish because I was quoting lines from her songs and I was like, 'Where did you come up with that? What's the meaning behind that?' She was physically weirded out. I know all the words to her new song."

It was recently confirmed that Swift is to appear at the ARIA Awards in Sydney on November 29.
